# DF-2231 run: privileged demonstrator via /dev/udev UDEVPROP.
# Must be run as ROOT (the only reachable caller on the default kernel).
# Usage: ./run.sh <len_hex> [mapmb]
#   len_hex = pref_len in hex  (e.g. 0x40000000 = 1 GiB)
#   mapmb   = optional; mmap a mapmb MiB source buffer at pref_plist so copyin
#             runs to completion (forces the kernel to hold the full allocation)
